I saw a video where the Ukrainian soldiers in the field jerry-rigged together a pretty cheap RC drone the proved to be very good at clearing out smaller land mines. It’s about the size of a scrunched up adult on wheels, with a small plow for a shield behind a big spinning tube with chains that just flail at the ground. It drives like an RC lawn mower, and has that big weed wacker tumbler on the front to trip antipersonnel mines while the soldiers just walk behind it a little ways so the shrapnel doesn’t get them. It worked pretty good, and didn’t require any crazy technology. Those troopers have gotten really good at using what they’ve got at hand to do the job. I hope they manage to push the Russians all the way back to sea and reclaim Crimea. Screw Putin and all of his BS.
